Spring mosses ( Fontinalis ) are a pleurocarp , more or less horizontally growing plant genus of flooding deciduous mosses, which can always be found under water to a depth of 20 m. The name Fontinalis translates as spring, because such mosses are often found in nutrient-poor source areas of rivers and lakes. Some representatives are used nowadays for aquariums and garden ponds .
features
Spring mosses can reach a total length of one meter, their trunk often forks and is often without leaves in the lower part. These are arranged in three rows and have no rib. The leaves are also somewhat egg-shaped to lanceolate, concave or flat, with entire margins or only have small teeth at the tip. The cells of the leaf surface are prosenchymatic and enlarged in the leaf corners. The seta of the capsules is very short, which is almost completely enclosed in a shell of parichaetial leaves . The capsule has a double serrated ring ( peristome ) and a cone-shaped lid.
